Warning: Immediates 21 and 32 will give undefined behavior.

[Frans Pop <elendil@planet.nl>]

During compilations using gcc-4.3 of the upstream 2.6.31-rc4 kernel, I
twice noticed the warning below. As the compilation was done with '-j4',
I'm not sure what code causes it. I'm also not sure if the example below
is the same as the first time I saw it.

Is this something to worry about, or to ignore?

The kernel config was 64-bits SMP.

Cheers,
FJP
